Comparing 2.4660 (Alloy 20) vs 1.4361 (Uranus S1) for 98% Nitric Acid HNO3

[hsbcn]

This is for the wetted parts of a swing check valve to be used in 98% Nitric Acid.

We're looking to compare the performance of Alloy 20 vs Uranus S1 at different temperatures of 98% nitric acid. Can someone shed some light on this issue? Screenshots/PDFs and the like would be really helpful.

Never heard of the 2nd alloy, and alloy 20's primary use is for sulphuric rather than nitric acid resistance.

Thanks for the feedback moltenmetal. As per the subject line, the werkstoff numbers (werkstoffnummer) for the two materials I'd like to compare are 2.4660 and 1.4361. Can anyone help with the comparison?
